极低出生体重儿适于胎龄儿与小于胎龄儿危险因素及并发症的比较

目的:探讨极低出生体重适于胎龄儿(AGA)与小于胎龄儿(SGA)的危险因素及并发症的特点及差异。方法:将125例极低出生体重儿分为两组,其中AGA组95例,SGA组30例,比较两组的危险因素及并发症的差异是否有统计学意义。结果:极低出生体重儿中AGA组和SGA组母亲妊娠期高血压疾病发生率的差异有统计学意义,其余危险因素两组间差异均无统计学意义,AGA组和SGA组新生儿并发症中新生儿呼吸窘迫综合征(RDS)和低血糖症发生率的差异有统计学意义,其余并发症发生率两组间差异均无统计学意义。结论:母亲妊娠期高血压疾病是极低出生体重SGA患儿发病的高危因素,极低出生体重SGA患儿RDS发生率低于AGA患儿,而低血糖症的发生率高于AGA患儿。

Comparison of risk factors and complications between small for gestational age infants and appropriate for gestational age infants among very low birth weight infants

Objective:To explore the characteristics and differences of risk factors and complications between appropriate for gestational age(AGA) infants and small for gestational(SGA) age infants among very low birth weight infants.Methods:A total of 125 very low birth weight infants were divided into two groups,including 95 AGA infants and 30 SGA infants,the risk factors and complications in the two gropes were compared.Results:There was statistically significant difference in incidence rate of pregnancy-induced hypertension syndrome(PIH) between AGA group and SGA group.But there was no statistically significant difference in the other risk factors between AGA group and SGA group.There were statistically significant differences in neonatal respiratory distress syndrome(RDS) and hypoglycemia between AGA group and SGA group.There was no statistically significant difference in the other complications between AGA group and SGA group.Conclusion:Maternal PIH is associated with SGA infants among very low birth weight infants,the incidence rate of RDS among SGA infants is lower than that among AGA infants,and the incidence rate of hypoglycemia among SGA infants is higher than that among AGA infants.
